MATTIE Sheridan cared for his wife for almost a decade, but had to put her into a home after his grant failed to come through.
His wife Bridie, now 67, was diagnosed with dementia when she was 58.
Mr Sheridan, from Water-ford, described how she could no longer walk to the local shopping centre for a chat with her friends.
"She could do nothing. I couldn't leave her on her own," he said.
Mr Sheridan applied for a grant three years ago to adapt the bathroom, toilet and upstairs bedroom.
He eventually accepted the Nursing Homes Support Scheme after being informed that it was unlikely he would receive a full grant.
The pensioner said he was particularly outraged at the increase in the age limit for those eligible for grants.
"My wife got dementia when she was 58," he said. "There's people getting it younger now."
